no worries.

changing rod bearings is a key element to insuring the longevity of our engines. Porsche determined a clear susceptibility of failure after re-tightening of the rod bolts in that part of the rod... not sure how they test for microscopic cracking at the factory, but cracking or clear cut failues were discovered... it sounds like Porsche became suspicious of the early connecting rods possibly when they were developing the Turbo S/RS, but that's just a guess.

thanks !!

my car was completed late in the same month. doubt if i got the new rods though.

So how about the rods in the 944 s2 3.0 ??? couldnt you just install those? Or is the weight different? I just purchased a red s2 cab, and plan to supercharge it, as long as it has the good rods that is ?????????

From PET it appears that S2 rods are the same as early 968 bendy rods.

I ain't so sure about supercharging either motor without serious work. Piston skirts are short. At least the 968 has squirters. I would suggest 951 rods and the bigend oil squirter mod at the very least. One might manage with E85 or water injection but I think it's pretty dangerous out there.

My 91' S2 had the fail prone 1R rods in it.

I had the early rods in a 968 motor that spent 2 years in my race car running constantly between 5000 and 7500 rpm for hours on end. Swapped them eventually as part of a bigger upgrade, but never had a problem. Would be interesting to have them crack tested I suppose, but they look fine. Supposedly a weaker design, but in practise it doesn't mean they will automatically grenade a motor. If I had them in a street car I wouldn't worry about them personally.

I agree about them being OK in a street motor if one is careful about getting good gas and being mindful of ping on hot days. S2s never seemed to have a problem with them so maybe it's the extra compression in the 968.

I want to get back to this old thread,

I was about to change the rods bearing in my 968 93 and found that the rods are one use only.

I am wondering if somebody used 944 early or Turbo rods in a 968 application with succes or if there could be a problem.

I search an alternative to the 2R or Carillo rods.


Problems with the squirters?
